I legit loved this app. However, the developer does not keep up with iOS updates, which is obvious when, after a software update, the app no longer works. The developer is unresponsive to messages about the status of the app.
Eleven months ago I had the same problem due to an iOS update, and I had to figure out how to track the developer down. I finally found them on Facebook messenger. This time, they are also unresponsive to Facebook messenger. I have deleted and reinstalled this app several times, and it still does not work correctly. I about give up on this app. And I was its top user.
